Interesting; the Eurofighter does have a very high T/W ratio; 1.66 for empty weight (I'm not sure how you arrived at 1.76) and 1.14 for loaded. The F-22 does retain a TWR advantage against the F-16 and Rafale, nevertheless. I agree that TVC isn't the holy grail for sustained agility, but can be a lifesaver at times.

The J-20 may not have TVC or adequate engines as of now, but if we are to assume that it will sooner or later adopt the WS-15 turbofans, with TVC and 180 kN thrust, its theoretical TWR with an empty weight reaches up to 2.08.

The T/W is for blowers which is the most likely scenario in a knifefight

In that case for the sake of the J20 let's hope the bogey is not a Typhoon, Rafale or blk 52 + Viper LOL hehehe at gun range I think these 4th Gen holds a slight advantage

Before or after they ran out of fuel after trying to dodge away from the J-20's BVR turkey shoot while watching their buddies getting blown to bits? By that time any survivors left would turn tail for home ASAP. Remember the J-20 has a higher fuel capacity and very manuavable as well.;)

Hmm because J20 doesn't have TVC and does not have a higher T/W ?

Maximum T/W:
F-22 = 1.61
Typhoon = 1.76

Rate of Climb:
F-22 = 200 m/s
Typhoon = 315 m/s

Instantaneous turn rate/Sustain turn rate:30~35/>20(degree/sec)

In a one on one match within gun range I would hazard a guess and say Typhoon holds an advantage over the J20. It is about parity to Raptor WVR but only because the Raptor has 2D TVC but even then the wrong application of TVC could prove disastrous for the Raptor because of sudden and immense loss of energy and in WVR energy management is everything .

Hard to see how anyone could arrive at an objective conclusion when they only have half a picture.

The T/W ratio and turn rates of the J20 are completely unknowns at this point in time.

Lack of TVC is also an invalid criticism, neither the Typhoon or Rafale uses it, so why does the J20, which uses the same delta-canard aerodynamic configuration, need TVC to achieve similar levels of agility?

The F22 need to use its TVC in a knife fight with Eurocanards because it uses a more traditional basic configuration, which is inherently less agile than a canard-delta.

You are also basing your entire premise on the assumption that the whole fight will happen like some quant knightly dual where both parties will arrive at an agreed area at the same time, doff their hats to each other before commencing.

But in reality, a good 5th gen fighter pilot will be exploiting the stealth of his machine to the max to get on his non-stealthy opponent's tail to finish the dogfight before his opponent even knew he was in one.

Rate of Climb:
F-22 = 200 m/s
Typhoon = 315 m/s
350 for F-22 !

The more nervous also
Rafale 305
Su-35S about 300
Mig-29/35 300/330
T-50 actual datas... 330 with futur engines 350
On Sputnik J-20, 304
J-10 285

All others 4th gen 230/260 m/s

Interesting coversations gentlemen, as of today, the J-20 is roughly the equivalent to the F-35 as far as WVR agility, the slight edge likely goes to the T-50, followed by the F-22, followed by the "Phoon"? The Raptor remains "dominant" in every realm of A2A combat, and is in NO way handicapped by it 2D OVT in spite of lots of "hyperbole"

and Equation, the idea that the J-20 will stand off and enjoy a turkey-shoot, is a scenario right out of "Peter Pan". That could occur against 3rd gen, or even 4th gen Western aircraft, and you are assuming a "home team advantage of Plenty of Fuel for the J-20,,,,,, the F-35 and the F-22 are very "Stealthy" and it is most unlikely that the J-20s radar or sensors would be in any way superior to those of the Western Aircraft??

this "hyperbole" continues to be blown around the Sino Defense Forum as the gospel, and nothing could be further from the truth, even with very high performance WS-15 with OVT??? very unlikely in the near term???? I would choose a seat in the Western fighters as opposed to the J-20 or T-50?? not only do I want to win??? more importantly, I want to LIVE!

Yeah that's what the naysayers and doubters always say in just about everything Chinese until China showed how their technology HAD reach par or beyond Western tech.

J-20 is also stealthy and as far as radar and sensors are concern no body knows for sure, but I would bet it can hold its own pretty good. The canards makes it more maneuverable than the F-35

I would also note that Military Professionals, mostly pilots/engineers are well able to extrapolate performance data base on known thrust and weight ranges, and "eyeball" the winner. Most internet phan bois are NOT objective, and live in the world of Smoke and Mirrors, I would take their conclusions with a "grain of salt".

For those of you who use the "teaspoon or tablespoon of salt concept", the grain of salt constitutes the minimal value of a concept, while a teaspoon or tablespoon would imply more value, rather than less.
Yes English is a difficult language, but not nearly as difficult as Chinese? LOL
